Collector notes

Visiting a coin shop

A few notes before you walk into JJ Diamond Buyers in New York, NY. These rotate daily. They are general collector etiquette from CDXList — not this shop’s house rules. When something is unclear, ask the person at the counter.

  1. What happens at the counter is private

    Do not repeat another customer’s name, address, or what they sold. Do not film the register. Shops are small towns. Discretion is part of being a decent visitor. It is also how you get treated like one.

  2. A written inventory helps on an estate

    Even a notebook list is better than a surprise pile. Heirs who write down what they think they have get a cleaner visit. If you are the executor, bring that fact and any papers. The shop can work faster when they are not inventing the catalog with you.

  3. Decide how you want to be paid before the offer

    If you are selling, know whether you need cash today, a check, or time to think. Changing the method after they have made a number can change the number. A clear “I would like a check if we agree” at the start saves a second conversation.

  4. “Best I can do” is a sentence, not an insult

    They have to sell it, hold it, and stay in business. You can say no. You can ask if they can do better on part of the lot. You should not treat a firm number as a personal slight. A calm “I need to think about that” is enough.

  5. Show week can empty the shop — or pack it

    If the dealer is on the road, the store may be closed or on shorter hours. If they just got back, they may be unpacking. Check this listing for upcoming shows and call if your visit is important. It is not personal. The bourse is part of the business.
